Doctors say that the Desalinated water supplied by kharamaa is safe for drinking and for other purposes.Still many people in Doha use bottled water for drinking.Now a days many families started installing RO systems (Reverse Osmosis) in their homes which further purifies the water making it more safe, by eliminating the contamination through the water supplying pipes etc. Desalinated water causes hair loss in many. U can consult a dermetologist for this problem.
